A method for deblocking at least one boundary of a coding unit, wherein the boundary forms a first side and a second side of the coding unit, wherein a video picture comprises the coding unit, and wherein the first and second sides use a same reference picture. The method includes obtaining a first motion vector component in the first side; obtaining a second motion vector component in the second side; determining whether an absolute difference between the first motion vector component and the second motion vector component is equal to or larger than a predetermined threshold that is less than 1 sample; and as a result of determining that the absolute difference between the first motion vector component and the second motion vector component is equal to or larger than the predetermined threshold, applying deblocking to the vertical or horizontal boundary between the first side and the second side.
Legal claims defining the scope of protection, as filed with the USPTO.
10. The method of claim 1, wherein the predetermined threshold is reduced when a specific coding tool is used for coding the video picture.
11. A non-transitory computer readable medium storing a computer program comprising instructions which, when executed by processing circuitry, causes the processing circuitry to carry out the method of claim 1.
14. The apparatus of claim 12, wherein the apparatus is an encoder or a decoder.
